How to improve iPhone battery life

“Why is my iPhone battery draining so fast?” This is a question Asurion Experts answer often while helping our 300 million customers (and counting!) get the most out of their devices, appliances, and tech every day. In this article, we’ll walk you through their recommendations for how to save battery life on your iPhone.

How to see what’s draining your iPhone battery

There’s an easy way to check and see which apps are the main culprits for causing your iPhone battery to drain quickly. Tap Settings > Battery to see a list of each app and how much battery it’s used in the last 24 hours or over a number of days. Or, tap Show Activity to see how much time’s spent in each app, and how long it’s been active in the background.

6 ways to improve iPhone battery life

Check for battery life suggestions

When your iPhone notices that you’re using more battery than usual, you’ll see battery saving suggestions based on your habits. Tap Settings > Battery > Battery Life Suggestions.

Check push notification settings

Push services can be a handy way to stay connected with the world. But your phone constantly searching for updates in the background can come at the expense of your battery life. Do a quick audit and see which push services you can live without to extend iPhone battery life. Tap Settings Notifications. Tap any app from the list to adjust push notification settings.

Adjust Auto-Lock settings

Auto-Lock sets the amount of time it takes for the phone screen to turn off. The faster the screen turns off when idle, the longer the battery will last.

  • Open Settings and tap Display & Brightness.
  • Tap Auto-Lock.
  • We recommend selecting 30 seconds. When the phone is inactive for 30 seconds, the screen will automatically shut off.

Adjust location settings

Location Services uses cell towers, Wi-Fi, GPS, and Bluetooth to pinpoint the phone for location-based features. These services can also burn through the battery.

  • Open Settings and tap Privacy.
  • Tap Location Services to see a list of the apps and their location access.
  • For most apps, choose NeverWhile Using the App, or Always.

Keep in mind that some apps won’t function properly without Location Services (like Maps and Weather). We recommend selecting While Using the App (if available) to save battery without sacrificing functionality.

Turn off Background App Refresh

You may not realize your iPhone is burning through data when apps and services you don’t need continuously run and update in the background. Most smartphones provide options to monitor or turn this function off, which will surely maximize battery life. 

  1. Go to Settings.
  2. Tap General.
  3. Tap Background App Refresh.
  4. Turn off Background App Refresh completely by toggling it off – you also have the option to set it to refresh an app only while using Wi-Fi or while using Wi-Fi & Cellular Data.

Flip on Low Power Mode

If you’re in a pinch and need your battery to last until you can get somewhere to charge it, turning on Low Power Mode is an easy solution that will help extend battery life. Keep in mind that some functions like mail fetch may be turned off in the process. Tap Settings > Battery > Turn on Low Power Mode.
